DETAILED DESCRIPTION OF THE EMBODIMENTS

The core of the present disclosure is to provide a face shield to reducethe facial injury to the wearer while satisfying the protectionrequirements.

Embodiments described hereinafter do not intend to limit the scope ofthe present disclosure as defined in the claims. Further, the entirecontents of the configurations described in the following embodimentsmay not be necessary for the solutions of the present disclosure definedin the claims.

Referring to FIGS. 1 to 3, the face shield of the present disclosureincludes a face shield body 100, an eye mask body 200 and a headband300, the face shield body 100 is transparent, and the face shield body100 has an eye area 102 in correspondence with the eyes and a face area101 in correspondence with the face; the eye mask body 200 extends fromthe eye area 102 along a thickness direction of the eye mask body, ahollowed-out area 201 is provided in the middle of the eye mask body200, and the eye mask body 200 is of an elastic body structure capableof elastic deformation under pressure; and the headband 300 is providedon the face shield body 100 and configured to secure the face shieldbody 100 to the head, and when the headband 300 is sleeved on the head,an end face of the eye mask body 200 away from the face shield body 100can fit with the periphery of the eyes.

When the face shield of the present disclosure is used, the face shieldbody 100 is secured onto the head by the headband 300, the face area 101of the face shield body 100 is in correspondence with the face, the eyearea 102 of the face shield body 100 is in correspondence with the eyes,and the eye mask body 200 is pressed so that the end face away from theface shield body 100 fits with the periphery of the eyes. Since thehollowed-out area 201 is provided in the middle of the eye mask body 200and the face shield body 100 is transparent, the face shield integratesthe functions of the protective face mask and the protective goggles,which greatly reduces the weight of the protective appliance and reducesthe facial injury to the wearer while satisfying the protectionrequirements.

It should be noted that the face shield body 100 has a planar structureor a curved surface structure. Preferably, the face shield body 100 hasa curved surface structure, which makes the face shield body 100 have awide visibility range. Alternatively, the face shield body 100 has aplanar structure before being worn, and when worn, the face shield body100 changes into a curved surface structure under the pulling force ofthe headband 300. Any structure of the face shield body 100 capable ofprotecting the face is within the protection scope of the presentdisclosure.

The face shield body 100 of the present disclosure not only has thefunction of face protection. In addition, a portion of the face shieldbody 100 in correspondence with the hollowed-out area 201 does notaffect the normal field of vision, and in combination with the eye maskbody 200, is equivalent to the function of the goggles. Since the eyemask body 200 is of the elastic structure and is deformed when pressed,the eye mask body 200 can be kept sealed around the eyes, so as toachieve the purpose of eye protection. It can be seen that the faceshield body 100 of the present disclosure in combination with the eyemask body 200 can be used as the goggles. Besides, some wearers havelimited vision. With regards to this, the hollowed-out area 201 enclosedby the eye mask body 200 has enough space for wearing short-sightedglasses, far-sighted glasses, and various glasses. The wearer can stillhave a clear vision even when wearing glasses.

Alternatively, in order to improve the protection level, thehollowed-out area 201 enclosed by the eye mask body 200 may be largeenough for wearing goggles.

In a case that the face shield is worn in a circumstance with a largetemperature difference, the portion of the face shield body 100 incorrespondence with the hollowed-out area 201 will fog up, therebyaffecting the wearer's field of vision. In order to reduce fogging, aninner face of the face shield body 100 in correspondence with thehollowed-out area 201 is coated with a first anti-fog coating. In orderto reduce the processing difficulty, the entire inner surface of theface shield body 100 is coated with the first anti-fog coating. Further,when a temperature difference occurs in the circumstance, an outersurface of the face shield body 100 may also fog up. In order to reducethe probability of fogging on the outer surface of the face shield body100, the outer surface of the face shield body 100 is coated with asecond anti-fog coating.

The face shield body 100 is made of lightweight plastic to reduce thepressure on the wearer. Preferably, the face shield body 100 is made ofPET.

The function of the eye mask body 200 is to ensure a tight seal aroundthe eyes, so as to meet the protection requirements of the goggles. Theeye mask body 200 is of an elastic structure, for example, it is made ofsponge or latex. When the headband 300 tightens the face shield, asqueezing force is generated between the eye mask body 200 and thewearer's face. Since the eye mask body 200 is of the elastic structure,the eye mask body 200 can be deformed correspondingly to the curvesurface of the wearer's face to ensure the fit with the face and improvethe sealing. In addition, since the sponge and latex are soft, it isrelatively gentle when the eye mask body 200 is pressed against theface, and the sense of pressure is also light.

Specifically, an end face of the eye mask body 200 away from the faceshield body 100 has a first fitting surface that fits with an upperportion around the eyes, a second fitting surface that fits with a lowerportion around the eyes, a third fitting surface that fits with a leftportion around the eyes, and a fourth fitting surface fits with a rightportion around the eyes. The first fitting surface, the second fittingsurface, the third fitting surface and the fourth fitting surface canensure the isolation of the eyes from the outside, and shapes of thefirst fitting surface, the second fitting surface, the third fittingsurface, and the fourth fitting surface are in correspondence with thecorresponding surface of the face.

In order to isolate a vent hole of the nose from the hollowed-out area201, the eye mask body 200 has an upwardly recessed nose wing portion.The nose wing portion isolates the hollowed-out area 201 enclosed by theeye mask body 200 from the vent hole of the nose. In this way, whenworn, the eye mask body 200 is located above the nose, the nose is notin the hollowed-out area 201 enclosed by the eye mask body 200, and thevent hole of the nose may be isolated from the hollowed-out area 201, sothat the air exhaled by the wearer is vented from a lower end of the eyemask area. Therefore, the problems of goggles fogging up, visibilitybeing reduced, and the sight being hindered, which are caused by part ofthe air escaping from two sides of the nose wing portion due to longterm operation or communication while wearing the face shield, can beavoided.

In order to ensure the protection level, the face shield body 100 is ofan integrated structure, and the eye mask body 200 and the face shieldbody 100 are bonded together, so that the face shield body 100 is freeof perforation, which further ensures the sealing effect of the eye maskbody 200 and the face shield body.

The headband 300 is directly bonded to the face shield body 100, or twoends of the headband 300 are provided with rivets, and the face shieldbody 100 is provided with mounting holes for mounting the rivets.Alternatively, the face shield body 100 is provided with rivets, and theheadband 300 is provided with mounting holes cooperating with therivets. Any configuration capable of realizing detachable assembly ofthe headband 300 with the face shield body 100 is within the protectionscope of the present disclosure. In addition, the headband is made of aninelastic material, or in order to improve the comfort of the wearer,the headband 300 has an elastic band structure.
